Qualitative research in dental public health: roles, problems and contributions to evidence-based dentistry
1. Introduction
Qualitative research is relatively uncommon in health care research, however it is now receiving recognition and increasingly used in health care research with social and cultural dimensions (Al-Busaidi 2008). In dentistry, the potential of qualitative research is enormous and only a few dental studies have been conducted using qualitative research methods (Stewart et al. 2008; George, Kruger & Tennant 2012).
Quantitative research is usually deductive and examines phenomena in terms of trends and frequencies, while qualitative research understanding the meaning of a phenomenon through description. Nevertheless, for …show more content…
In identifying and describing organizational changes that affect outcomes, including organizational culture, clinical leadership, and team-based interactions, qualitative method can be used (Bower & Scambler 2007). For example, the study about feasibility of implementing rapid oral fluid HIV screening in an urban University Dental as paradigm change for dentistry (Stewart, K, Gill, P, Chadwick, B, & Treasure, E …show more content…
Fortunately, Krause found a way to reach this goal. He explained a logical sequence for implementing the use of multiple qualitative techniques. First is about focus groups that are considered as a helpful method to understand how members of different social demographic groups discuss health-related issues among themselves. However, some individuals may unwilling to discuss sensitive health issues in a group. Hence, for this reason, the individual in-depth interviews can be used to supplement. After the focus groups and in-depth interviews have been conducted, draft preliminary items quantitative can be developed. Next, the items may be reviewed by a panel of experts. After revising the questions based on the input of the experts, a series of cognitive interviews can be conducted. The purpose of the cognitive interview is to see if study subjects understand the quantitative questions, to see if respondents can phrase question in a better way, and to see if subjects feel comfortable with the quantitative response options (Krause 2006). In the outcomes research, qualitative methods can be useful for development of patient-centered quantitative instruments. For example, the usage of qualitative methods in the initial stage of developing patient-centered quantitative measures of health-related constructs. The role of qualitative studies in this
